Instructions for Objective 5.7 and 5.8

1.    

5.7 and 5.8 Starter.  Find out the names of the processes.  Research on the internet if necessary.  No need to blog this.

2.    5.7 and 5.8.  Forward this e-mail to your blog and type the answers into the e-mail.

3.    5.7 and 5.8 Experiment.  I’m afraid you can’t do the expt until we get back but watch the video clip to see how it’s set up and have a look at the graph of the results.

4.    5.7 to 5.10 Plenary 1.  Play the attached “States of Matter”

5.    5.7 to 5.10 Plenary 2.  Play the attached “Fill the trucks”

6.    PhET States of matter simulation - embedding into your Posterous blog.  Embed in your blog and then have a play

·         

5.7 understand that a substance can change state from solid to liquid by the process of melting

·         5.8 understand that a substance can change state from liquid to gas by the process of evaporation or boiling

·         Questions from Collins p.112

·         Answer in Bullet Points!

1a. Liquids and gasses loose their shape because the structures of the atoms are not in a fixed pattern and therefore, the bonds are more free and the particles are able to move freely. 

b. This is because solids and liquids do have bonds between them and have an almost fixed pattern. Gasses fill their container because they have no bonds and therefore their shape can be changed to fit the container. 

  

Evaporation happens when the air gets hotter and gives the particles on the surface of the water gain kinetic energy and break apart from the bonds and turn into a gas. 

Boiling happens when when the temperature of the liquid reaches the boiling point. Its a fast process that breaks the bonds of the particles and turns them into a gas.
